Hello and thanks for your post.
The application process is truly holistic, and committees will look at your stats (GPA and GMAT), work experience, and extracurriculars.
Your GPA is strong and your GMAT is excellent, so you definitely have the stats to impress the admissions committee. However, that is just one component.
It is hard to gauge your work experience without knowing your accomplishments and impact you have made there. It will be important to show you have made an impact and demonstrated leadership there. Ideally this will be supported by strong recommendation letters as well. It will also be important to explain why you want your MBA after working for 7 years, and to also illustrate the skills you already have which are transferable to your post-MBA goals. Be sure your story makes sense, and is realistic and specific.
Regarding extracurriculars, make sure to really emphasize your leadership roles you have taken on.
In general, I suggest apply to several schools, including reach, target and safety. So you may want to apply to more than one school, just in case.
Good luck!
